Answer:

D. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.

Explanation:

Water moves in the cells through osmosis which means water moves from its higher concentration to lower concentration. In many animals and plants, water channels are also present which is called aquaporins which allow the water to move through it in and out of cell more quickly.

The rate of diffusion by channel proteins is higher than simple diffusion therefore the aquaporins speed up the process of osmosis. No ATP is required to transport the water through aquaporin channel proteins.

True or false the genotype of an organism constitutes its observable characteristics

iren2701 [21]

False

The genotype of an organism does not constitute its observable characteristics but rather its phenotype. A genotype of an organism is the genetic makeup of an organism while the phenotype is the visible characteristics.
It is, however, significant to understand that the phenotype of an organism is as a result of the interaction between the genotype and the environment.
